• Clean the area between the belt and the deck 

Lubricate the belt and deck 

• Use a silicone lubricant spray, liquid, or wax

• Apply the lubricant to the top of the running deck

• Clean underneath the deck before applying lubricant

“MAINTENANCE Regular maintenance is important for optimal performance and to reduce wear. Inspect and properly tighten all parts each time the incline trainer is used. Replace any worn parts immediately. Regularly clean the incline trainer and keep the walking belt clean and dry. First, press the power switch into the off position and unplug the power cord. Wipe exterior parts of the incline trainer with a damp cloth and a small amount of mild soap. IMPORTANT: Do not spray liquids directly onto the incline trainer. To avoid damage to the console, keep liquids away from the console. Then, thoroughly dry the incline trainer with a soft towel.”

PLEASE ALSO NOTE: “Your incline trainer features a walking belt coated with high-performance lubricant. IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform unless instructed to do so by an authorized service representative. Such substances may deteriorate the walking belt and cause exces- sive wear. If you suspect that the walking belt needs more lubricant, see the front cover of this manual.” Home treadmill maintenance and repair

Lubricate the deck every 150 miles so the belt won’t wear out. Use an Allen wrench to loosen the bolts in the back of the treadmill by turning them counter-clockwise. This will loosen the belt so you can lift under it.[2] Then, lift the belt and apply 1 ounce (28 g) of silicone lubricant spray, liquid, or wax to the top of the running deck.[3]This will keep the belt from causing too much friction as you walk or run.[4]

• Some treadmills are self-lubricating and don’t need to be sprayed or waxed. Make sure you check your owner’s manual before applying a lubricant.[5]

• While it’s rare, some brands require a specific type of wax or spray. Check your owner’s manual to make sure you use the right type of lubricant.[6]

• Make sure you don’t spray the lubricant on top of the belt, as it can make the belt slippery.[7]

Tighten the belt as needed to maintain the tension. If the belt on your treadmill feels like it’s wiggling around too much, it’s likely that the belt has stretched a bit and needs to be tightened.[8] On most machines, there are 2 bolts at the end of the deck that you can tighten with an Allen wrench by adjusting the bolts clockwise.[9]

• There is no set amount of time after which you’ll need to tighten the belt. Instead, do this as needed whenever you feel like the belt is wiggling or sliding and making it more difficult to use the machine

Align the belt if it doesn’t run straight down the deck. In addition to stretching, the belt on your treadmill may slide off the center of the deck over time. On most machines, you can easily realign the belt by adjusting the bolts located on either side of the back of the machine. To do this, use an Allen wrench to adjust the bolts clockwise or counter-clockwise (depending on how the belt needs to be aligned) until the belt aligns in the center of the deck again.[10]

• Because every machine is different, making sure that you check the owner’s manual to see how to align the belt on your particular treadmill.
